Do I have a diaclone?

About a year and a half ago I picked up a G1 Mirage (Goodyear tires variant) from the Pasadena Flea Market. Somebody at work told me that this was the Diaclone version. Is this true? Also, it does not have a rub symbol.

Bought it loose with no accessories, I cannot remember if it came with all of the stickers, and I do not have a camera right now. Also, it does not have the HASBRO seal on the bottom it just has TAKARA 1982.
